John Huebner’s reply and this post sent me into the right direction:

Modified it for gallery field.

function my_save_post( $post_id ) {
        //attachment to media gallery 
	$my_files = get_field('my_gallery', $post_id);	

	if($my_files){

		foreach( $my_files as $my_file ):
			$file_id = $my_file['ID'];
			$post_to_update = array(
				'ID'           => $file_id,
				'post_parent'  => $post_id
			);
			wp_update_post( $post_to_update );
		endforeach;
	}
}
add_action('acf/save_post', 'my_save_post', 15);
